Question for Waltr

[6666]

Hi Waltr recently you published a spice circuit, looks like I did not keep the spice file, would you mind attaching it again please.

No problem and I actually found this spice model on on hard drive.

Does the circuit work for you? Need to play some more but I'm having problems.

Ahhhh.....
What I just posted is not exactly the same as what 6666 asked for.
I added some components (D3, R1, D4 & R2) to look at possible damping methods that have been under discussion.
Otherwise, yes, this circuit does run the simulation and works.

The integrator section does work, just need to run for a longer time since it takes many TX cycles to build the integrator output Voltage.
Coil damping R values may also need adjusting.

In general this spice model does work very close to actual circuit I have built. Good enough to play with other concepts.

Thanks Waltr much appreciated.
